Description

BACKGROUND

1. Field

[0001] The present invention relates to a fabric treatment apparatus and a control method of a fabric treatment apparatus.

2. Background

[0002] A fabric treatment apparatus, which is an apparatus for treating fabric, may be classified as a washer for removing contaminants from fabric using water and detergent, a dryer for applying hot air or cold air to wet fabric to dry the fabric, or a refresher for spraying water to fabric in the form of steam or mist to unwrinkle or deodorize the fabric and thus to manage the fabric in a more comfortable state. In recent years, complex apparatuses, such as a dryer and washer and a washer or a dryer having a refreshing function, which are capable of complexly performing functions of the above-mentioned apparatuses, have also been widely used.

[0003] For a fabric treatment apparatus having a drying function, however, the temperature of fabric is steadily increased as drying of the fabric is progressed with the result that the fabric may be overdried. Particularly for a fabric treatment apparatus that dries fabric while a drum, in which the fabric is placed, is rotated, moisture may be removed from the fabric and thus the volume of the fabric may be increased as drying of the fabric is progressed when the amount of the fabric is large with the result that the fabric may not be uniformly mingled. Consequently, the temperature of the fabric placed near a hot air discharge port may be excessively increased and thus more moisture than necessary may be removed from the fabric or the fabric may shrink, may be discolored, or may be denaturalized due to rapid removal of the moisture or overheating.

SUMMARY OF THE INVENTION

[0004] It is an object of the present invention to provide a fabric treatment apparatus and a control method of a fabric treatment apparatus that is capable of preventing the temperature of fabric from being excessively increased during drying of the fabric.

[0005] The object is solved by the features of the independent claims. In accordance with one example, a control method of a fabric treatment apparatus having a drying function includes supplying high-temperature hot air into a treatment space, in which fabric is treated, through operation of a drying heater, sensing a temperature of the treatment space, and spraying steam into the treatment space through a steam spray device when the sensed temperature of the treatment space is equal to or greater than a set temperature. The high-temperature air or hot air refers to air heated by a (drying) heater, i.e. to heated air.

[0006] The step of spraying the steam may include spraying the steam for a predetermined time and/or spraying the steam intermittently. The step of spraying the steam may include spraying the steam for 10 to 20 seconds every 2 to 3 minutes.

[0007] The step of spraying the steam may be performed until a predetermined drying completion condition is satisfied.

[0008] The control method may further include stopping the operation of the drying heater when the sensed temperature of the treatment space is equal to or greater than the set temperature is equal to or greater than the set temperature. The steam spray device may include a steam generation heater for generating steam. In this case, the step of spraying the steam may include operating the steam generation heater for a predetermined time. The control method may further include stopping the operation of the steam generation heater after an elapse of the predetermined time. The drying heater may be operated again in a state in which the operation of the steam generation heater is stopped.

[0009] The set temperature may be about 65 °C.

[0010] The set temperature may be about 75 °C.

[0011] The step of supplying the hot air may include operating a blower for blowing air into the treatment space during the operation of the drying heater.

[0012] The fabric treatment apparatus may include a rotatable drum defining the treatment space. Here, the step of supplying the hot air may include rotating the drum such that the fabric is tumbled in the drum.

[0013] In accordance with another example, a fabric treatment apparatus includes a treatment space forming unit having a treatment space, in which fabric is treated, formed therein, a drying heater for heating air to be supplied to the treatment space, a blower for blowing the air heated by the drying heater to the treatment space, a temperature sensor for sensing a temperature of the treatment space, a steam spray device for spraying steam to the treatment space, and a controller for controlling the drying heater, the blower and the steam spray device to perform a method as described above. In other words, the controller is configured to control the drying heater and the blower to supply high-temperature hot air, i.e. heated air, to the treatment space and to control the steam spray device to spray steam when the temperature of the treatment space is increased due to the hot air supplied to the treatment space and the temperature of the treatment space sensed by the temperature sensor is equal to or greater than a set temperature.

[0014] The controller may control the steam spray device to spray the steam for a predetermined time and/or intermittently. The controller may control the steam spray device to spray the steam for 10 to 20 seconds every 2 to 3 minutes.

[0015] The controller may control the steam spray device to spray the steam until a predetermined drying completion condition is satisfied.

[0016] The steam spray device may include a steam generation heater for generating steam. Here, the controller may control the operation of the drying heater to be stopped and the steam generation heater to be operated for a predetermined time when the temperature of the treatment space sensed by the temperature sensor is equal to or greater than the set temperature. The controller may control the operation of the steam generation heater to be stopped. Also, the controller may control the drying heater to be operated again after an elapse of the predetermined time.

[0017] The set temperature may be about 65 °C.

[0018] The set temperature may be about 75 °C. The fabric treatment apparatus may further include an input unit for allowing selective input of at least one of a normal drying mode and a high-temperature drying mode. The set temperature when the high-temperature drying mode is selected through the input unit may be higher than the set temperature when the normal drying mode is selected through the input unit.

[0019] The treatment space forming unit may include a rotatable drum, in which the fabric is received. The controller may control the drum to be rotated such that the fabric is tumbled in the drum during supplying of high-temperature hot air to the treatment space.

To the cabinet cover 32 may be hingedly connected a door 28 for opening and closing the laundry introduction port.

[0025] The control panel 40 may be provided at the front thereof with an input unit 45 (see FIG. 6), such as a button and dial, for allowing a user to input various control commands related to operation of the dryer 1 and a display unit (not shown), such as a liquid crystal display (LCD) and a light emitting diode (LED), for visually displaying operation status of the dryer 1. The control panel 40 may be provided at the rear thereof with a controller 41 (see FIG. 6) for controlling overall operation of the dryer 1. In particular, a normal drying mode or a high-temperature drying mode may be selected through the input unit 45.

[0026] The dryer 1 may be provided with a container 72 for supplying water to a steam spray device 100 such that the container 72 can be withdrawn from the dryer 1. A drawer 71 may be supported by the cabinet 30 such that the drawer 71 can be withdrawn from the dryer 1 and the container 72 may be received in the drawer 71. The container 72 may have a water supply port 72a, through which water is introduced into the container 72.

[0027] In the casing, the casing is provided at the front part and the rear part thereof with a front supporter 10 and a rear supporter 8, respectively. The front and the rear of the drum 4 are supported by the front supporter 10 and the rear supporter 8, respectively.

[0028] The front supporter 10 is provided at the middle part thereof with an opening 50 communicating with the laundry introduction part. The front supporter 10 is provided at the rear thereof with a ring-shaped front support protrusion 54 for supporting a front end of the drum 4. In addition, the front supporter 10 is provided at the lower part thereof with a front guide roller 56 such that the front guide roller 56 is rotatable. The inner circumference of the front end of the drum 4 is supported by the front support protrusion 54 and the outer circumference of the front end of the drum 4 is supported by the front guide roller 56.

[0029] The rear supporter 8 is provided at the front thereof with a ring-shaped rear support protrusion 60 for supporting a rear end of the drum 4 and the rear supporter 8 is provided at the lower part of the front thereof with a rear guide roller 64 such that the rear guide roller 64 is rotatable. The inner circumference of the rear end of the drum 4 is supported by the rear support protrusion 60 and the outer circumference of the rear end of the drum 4 is supported by rear guide roller 64.

[0030] The drum 4 is provided at the lower side thereof with a drying heater 42 for heating air. A drying duct 14 is provided between the rear supporter 8 and the drying heater 42 such that the rear supporter 8 and the drying heater 42 communicate with each other via the drying duct 14 for supplying the air heated by the drying heater 42 into the drum 4. The front supporter 10 is provided with a lint duct 16 such that the lint duct 16 communicates with the front supporter 10 for allowing the air having passed through the drum 4 to be introduced thereinto.

[0031] The drying duct 14 is provided with a plurality of through holes 144, through which air is discharged into the drum 4. Air flows in the drum 4 via the lint duct 16, a blower 22, and an exhaust duct 20 due to blowing force generated by the blower 22. Particularly, in the flowing process of the air, the air heated by the drying heater 42 flows along the drying duct 14 and is then discharged into the drum 4 through the through holes 144.

[0032] In addition, the air introduced into the lint duct 16 is purified by a filter 18. The casing is provided at the rear thereof with an exhaust duct 20 for guiding the air from the lint duct 16 to the outside of the casing.

[0033] The blower 22 is connected between the exhaust duct 20 and the lint duct 16. The dryer 1 further includes a motor 24 for generating driving force of the blower 22 and the drum 4 and a transmission belt 26 interlocked with the motor 24 for rotating the drum 4.

[0034] Referring to FIG. 5, the steam spray device 100 includes a flow channel forming unit 160 having a flow channel, along which water introduced through an introduction port 140 is guided to a nozzle 170, formed therein, a steam generation heater 130 for applying heat to the water flowing along the flow channel formed in the flow channel forming unit 160, and the nozzle 170 for spraying steam generated by a heating operation of the steam generation heater 130 at a predetermined pressure.

[0035] The flow channel forming unit 160 may include a flow channel body 110 having a flow channel 111, along which water is guided from the introduction port 140 to the nozzle 170, formed therein, the flow channel body 110 being open at the upper part thereof, and a cover 120 for covering the open upper part of the flow channel body 110. According to embodiments, the flow channel body 110 and the cover 120 may be integrally formed. The introduction port 140, which is connected to a water supply pipe 74, is formed at the flow channel body 110. Consequently, water is introduced into the flow channel body 110 through the introduction port 140.

[0036] The flow channel forming unit 160 and the nozzle 170 may be integrally coupled to each other. Integral coupling between the flow channel forming unit 160 and the nozzle 170 may include a case in which the flow channel forming unit 160 and the nozzle 170 are formed as separate members and are then coupled to each other to constitute a single unit or module. Said integral coupling may also include a case in which the flow channel forming unit 160 and the nozzle 170 are formed as a single member by injection molding. In any case, the position of the nozzle 170 may be decided based on the fixed position of the flow channel forming unit 160.

[0037] In a conventional structure in which water contained in a predetermined container is heated to generate steam and the generated steam is fed to a nozzle along a hose, the steam is condensed during flowing of the steam along the hose. As a result, the condensed water is sprayed through the nozzle, whereby fabric is wetted. In this embodiment of the present invention, on the other hand, water is heated to generate steam during flowing of the water along the flow channel forming unit 160, the steam is sprayed through the nozzle 170 integrally formed at the flow channel forming unit 160. Consequently, it is possible to fundamentally prevent the occurrence of a phenomenon in which the steam generated in the flow channel forming unit 160 is condensed while being supplied to the nozzle 170.

[0038] Referring to FIG. 6, the dryer 1 may include a controller 41 and/or a temperature sensor 44. Preferably, the dryer 1 include the controller 41 and the temperature sensor 44 in addition to the input unit 45, the drying heater 42, and the steam generation heater 130.

[0039] The temperature sensor 44 senses the temperature of air in the treatment space, i.e. the drum 4. The controller 41 controls operations of the respective components of the dryer 1. In particular, the controller 41 may control the operation of the drying heater 42 and/or the steam generation heater 130 based on the temperature sensed by the temperature sensor 44. Control methods of a fabric treatment apparatus according to embodiments of the present invention described hereinafter with reference to FIGS. 7 to 9 are based on control of the controller 41 unless mentioned otherwise.

[0040] Control methods of a fabric treatment apparatus (for example, a dryer) according to embodiments of the present invention described hereinafter each include a hot air supplying step of supplying high-temperature hot air into the treatment space S, in which fabric is treated, through the operation of the drying heater 42, a temperature sensing step of sensing the temperature of the treatment space S, and a steam spraying step of spraying steam into the treatment space S through the steam spray device 100 when the sensed temperature of the treatment space S is equal to or greater than a set temperature. Hereinafter, the control methods of the fabric treatment apparatus will be described in more detail with reference to the accompanying drawings.

[0041] FIG. 7 is a flowchart showing a control method of a dryer according to an embodiment of the present invention. Referring to FIG. 7, the dryer 1 supplies hot air into the drum 4 to dry fabric (S11). At step S11, the drying heater 42 is operated and the blower 22 is rotated. During supplying of the hot air, the drum 4 may be rotated. At this time, the drum 4 may be rotated at a speed at which the fabric can be lifted to a predetermined height and then dropped, i.e. tumbled.

[0042] During supplying of the hot air, the temperature of air in the drum 4 is sensed by the temperature sensor 44 (S12). In the following description, sensing of temperature by the temperature sensor 44 may be continuously carried out until the drying of the fabric is completed.

[0043] When a temperature T sensed by the temperature sensor 44 is equal to or greater than a set temperature Tset (S13), the controller 41 controls the steam spray device 100 to spray steam for a predetermined time (S14).

[0044] Subsequently, the controller 41 determines whether a drying completion condition is satisfied to control the operation of the steam spray device 100. For instance, the controller 41 compares the temperature T sensed by the temperature sensor 44 with the set temperature Tset until a drying completion condition is satisfied to control the operation of the steam spray device 100 (S15 -> S13 -> S14). The drying completion condition may be a time passed after the drying heater 42 starts to be operated and/or determination as to whether humidity in the drum 4 is lowered to a predetermined level. In the latter case, the dryer 1 may further include a humidity sensor (not shown) for sensing the humidity in the drum 4. Alternatively or additionally, the dryer 1 may further include at least one temperature sensor provided in the hot air flow channel so as to estimate the humidity in the drum 4 based on a difference from the temperature sensed by the temperature sensor 44.

[0045] At step S14, the steam may be sprayed for a predetermined time. For example, the steam may be sprayed for 10 to 20 seconds; however, the present invention is not limited thereto.

[0046] When the drying completion condition is satisfied at step S15, the operation of the drying heater 42 is stopped (S16) and drying of the fabric is completed.

[0047] FIG. 8 is a flowchart showing a control method of a dryer according to another embodiment of the present invention. Referring to FIG. 8, the dryer 1 supplies hot air into the drum 4 to dry fabric (S21). At step S21, the drying heater 42 is operated and the blower 22 is rotated. During supplying of the hot air, the drum 4 may be rotated. At this time, the drum 4 may be rotated at a speed at which the fabric can be tumbled.

[0048] During supplying of the hot air, the temperature of air in the drum 4 is sensed by the temperature sensor 44 (S22). When a temperature T sensed by the temperature sensor 44 is equal to or greater than a set temperature Tset (S23), the controller 41 controls the steam spray device 100 to intermittently spray steam (S24). The steam spray device 100 may spray steam for a predetermined time, stop spraying of steam, and then spray steam, which may be repeated. For example, steam may be sprayed for 10 to 20 seconds every 2 to 3 minutes. Spraying of the steam (S24) is continued until the drying completion condition is satisfied (S25). When the drying completion condition is satisfied at step S25, the operation of the drying heater 42 is stopped (S26) and drying of the fabric is completed.

[0049] When the temperature T sensed by the temperature sensor 44 is lower than the set temperature Tset at step S23 and the drying completion condition is not satisfied at step S27, on the other hand, the procedure returns to step S23.

[0050] FIG. 9 is a flowchart showing a control method of a dryer according to a further embodiment of the present invention. Referring to FIG. 9, the dryer 1 supplies hot air into the drum 4 to dry fabric (S31). At step S31, the drying heater 42 is operated and the blower 22 is rotated. During supplying of the hot air, the drum 4 may be rotated. At this time, the drum 4 may be rotated at a speed at which the fabric can be tumbled.

[0051] During supplying of the hot air, the temperature of air in the drum 4 is sensed by the temperature sensor 44 (S32). When a temperature T sensed by the temperature sensor 44 is equal to or greater than a set temperature Tset (S33), the controller 41 controls the operation of the drying heater 42 to be stopped (S34).

[0052] A steam spraying step (S35) includes a step of operating the steam generation heater 130 in a state in which the operation of the drying heater 42 is stopped. The operation of the steam generation heater 130 may be performed in a condition that the operation of the drying heater 42 is stopped. Since the drying heater 42 and the steam generation heater 130 are not simultaneously operated but one is operated while the other is not operated, power consumption may be reduced. Consequently, the control operation according to this embodiment may be applied even to a case in which the amount of power supplied to the dryer is not sufficient and thus it is difficult to simultaneously operate the drying heater 42 and the steam generation heater 130.

[0053] After steam is sprayed for a predetermined time at the steam spraying step (S35), the controller 41 controls the operation of the drying heater 42 to be resumed (S36). The predetermined time may be 10 to 20 seconds; however, the present invention is not limited thereto.

[0054] Subsequently, when the drying completion condition is satisfied, the operation of the drying heater 42 is stopped and drying of the fabric is completed (S37 -> S38).

[0055] In the above embodiments, when the temperature in the drum 4 reaches a predetermined level, steam is supplied into the drum 4 to lower the temperature in the drum 4. Consequently, it is possible to prevent shrinkage, discoloration, and denaturalization of the fabric due to overheating.

[0056] In a case in which the input unit 45 for selecting a normal drying mode or a high-temperature drying mode is provided, the set temperature Tset may have different values based on selected modes at the steam spraying step of each of the embodiments. For example, the set temperature Tset may be about 65 °C in the normal drying mode and about 75 °C in the high-temperature drying mode.

[0057] FIG. 10 is a graph showing a comparison between a shrinkage rate (b) of fabric based on materials of the fabric in a normal drying mode of a dryer according to an embodiment of the present invention and a shrinkage rate (a) of fabric in a conventional dryer. FIG. 11 is a graph showing a comparison between a shrinkage rate (b') of fabric based on materials of the fabric in a high-temperature drying mode of the dryer according to the embodiment of the present invention and a shrinkage rate (a') of fabric in the conventional dryer.

[0058] As can be seen from FIGS. 10 and 11, the control method of the fabric treatment apparatus according to the embodiment of the present invention has a lower shrinkage rate of the fabric than the control method of the conventional dryer although the shrinkage rate of the fabric in the normal drying mode (FIG. 10) is different from the shrinkage rate of the fabric in the high-temperature drying mode (FIG. 11). This characteristic is commonly applied to the other embodiments previously described.
